“…The article [26] presented the results from measuring and calculating the isomeric ratios for the 87m,g Y nucleus produced in the 90 Zr(γ,2np) 87g,m Y and 91 Zr(γ,3np) 87g,m Y reactions, and for the 86m,g Y nucleus produced in the 90 Zr(γ,3np) 86g,m Y and 91 Zr(γ,4np) 86g,m Y reactions at Е γmax = 84 MeV. In the work, isotopically enriched targets were used.…”
